*Quartz silica glass can transmit far ultraviolet, transmit visible light and near infrared optical curve. Can stand higher temperature than 1000° C
* Main glass material type
--1. JGS1( Extreme UV optical quartz glass)
In particular in the shortwave UV zone and can achieve a 90% transmission rate at the wavelength of 185nm. Hence it is an ideal choice for applications in the wavelength range of 185-2500nm.
--2. JGS2 (UV optical quartz glass)
It is suggested for applications in the wavelength range of 220-2500nm.
--3. JGS3 (Infrared quartz glass)
It is recommended for applications in the wavelength range of 260-3500nm.
* Mainly apply in military, laser, metallurgical, optical instrument and stage light etc. High temperature window.
